Succession of Egeria densa in a drinking water reservoir in Morbihan (France)
Hydrobiologia, 1999Located in western France, the Pen Mur dam of Muzillac (Morbihan) is mainly used for the production of drinking water and for fishing. Over the past few years, the upstream part of this eutrophic waterbody has been invaded by Egeria densa. To define suitable methods for the management of this plant, a 1996 study focused on the morphometric ...

Symplast domains in extrastelar tissues of Egeria densa Planch.
Planta, 1985A set of hydrophilic fluorescent dyes of known molecular weight has been used to determine the molecular exclusion limit and the extent of apical, epidermal and cortical symplasts in the root, stem and leaf of Egeria densa. These dyes are unable to pass the plasmalemma, so that any cell-to-cell movement of injected dye must occur via the symplast.

A dynamic model for photosynthesis by an aquatic plant, Egeria densa
Plant, Cell and Environment, 1985AbstractThis paper describes a dynamic model for photosynthesis by an aquatic plant,Egeria densa.The model takes into account an HCO−3pump, high diffusion resistances and PEP carboxylase, and develops a set of differential equations to form the time‐dependent solutions for photosynthesis.

Ion distribution in leaf cells of Egeria densa.
Acta histochemica. Supplementband, 1991The lement concentrations of intracellular compartments of leaf cells of Egeria densa are estimated by X-ray microanalysis. Ultrathin frozen-dried sections are used in TEM mode. The concentrations of Na, Mg, P, Cl, K, and Ca are determined in the cell wall, cytoplasm and chloroplasts.

Quiescence, growth and senescence of Egeria densa in Lake Marion
Aquatic Botany, 1984Abstract Seasonal changes in biomass production and morphology of the submersed vascular plant Egeria densa Planchon (Brazilian elodea) were followed in Lake Marion, South Carolina, from march 1980 to May 1981. Biomass maxima occurred in late summer and late fall; these were followed by periods of senescence denoted by biomass loss through sloughing ...

Malate synthesis and metabolism during photosynthesis in Egeria densa planch
Aquatic Botany, 1980Abstract During pulse-chase labelling experiments at air levels of CO 2 (pH 4.5; 13 μ M CO 2 (aq.)) Egeria densa Planch. fixed 20% of its photosynthetic carbon by β-carbboxylation into the C-4 of malate. Further label, which entered the malate pool via the three carbon precursors, was derived from secondary photosynthetic products (sugar ...

Identification of myosin in a flowering plant, Egeria densa.
Journal of biochemistry, 1979A myosin-like protein was extracted and partially purified from a flowering plant, Egeria densa. It had no p-nitrophenyl phosphatase activity, but exhibited EDTA(K+)-ATPase [EC 3.6.1.3] activity at high ionic strength. Its molecular weight as estimated by gel filtration was 4-5 X 10(5).
